Makes me wonder how many passengers genuinely stop to think before answering.
Very true Koncordski.
"Could anyone of interfered with your bag since it was packed?"
Stock answer. "No."
Reality. "Yes" - The hotel porter while it was in the baggage room. Someone in the office while it was unattended beside my desk. Someone on the train while it was on the HEX luggage rack................
I would guess that a huge majority of bags that go through airports every day have been out of sight of the pax at some time since they packed them.
